Installation Instructions

The threshold adapter eliminates any tripping hazard and protects the bottom track when the Plissť is mounted in a door opening where the bottom track rests on top of the existing threshold.

The threshold adapter is not needed if the point where the bottom track is to be mounted is lower than the existing threshold. On sliding doors it is often not needed because there is usually a lowered place for the original screen track.

This threshold adapter is suitable for single Plissť screens 36-60" wide.
